The Grand Tour1
Toshiba provides two interface units that integrate the Strata DK telephone system 
with PCs, printers, and modems for a variety of applications.
The Stand-alone Data Interface Units (PDIU-DS) normally connects to printers and 
modems so that they can be shared by all users via data calls through the DK 
telephone system.
The telephone PC Interface Unit (RPCI-DI) is built into the base of the digital 
telephone and connects to the COM port of a PC. There are two operating modes:
©Telephone Application Program Interface (TAPI) mode
©Data communication mode
The PC TAPI software program automatically controls the operation mode (TAPI or 
Data Communications) of the RPCI.
A 2B+D ISDN-type digital link in conjunction with the RCPIs and DIUs enable 
digital telephones to participate in simultaneous voice and data calls. Voice and data 
calls are transmitted over the same digital telephone wire pair. This offers you several 
calling options. For example, a digital telephone user can place a voice call while in 
the middle of a data call to a printer or host computer, etc.
This chapter lists all the equipment required to originate or receive a data call. In 
addition, it explains the function and configuration of the Data Interface Units (DIUs), 
both the RPCI-DI and PDIU-DS types.

Hardware Requirements

Hardware Requirements
The following hardware is required to originate a data call:
©A RPCI-DI (replaces digital telephone base)
©A PC or ASCII Terminal
©One of the following Toshiba 2000- or 1000-Series Digital Telephones:
©DKT2010-H (10-button model)
©DKT2010-SD (10-button model with a LCD and speakerphone)
©DKT2020-S (20-button model)
©DKT2020-SD (10-button model equipped with LCD and speakerphone)
©DKT1010-H (10-button model)
©DKT1020-SD (10-button model equipped with LCD and speakerphone)
A data call can be made to a device connected to a DIU (RPCI-DI or PDIU-DS), such 
as mainframe computers, printers, modems, PCs, and ASCII terminals.
Integrated Data Interface Unit (RPCI-DI)
A telephone within the Strata DK system that participates in a data call must be a 
Toshiba digital telephone equipped with an integrated DIU (RPCI-DI). A label 
reading “MODEL RPCI-DI” on the bottom of the telephone and an RS-232 connector 
on the back of the telephone both indicate that a telephone is equipped with a RPCI-
DI. See Figure 1.
NoteThroughout this guide, RPCI-DI-equipped digital telephones that are 
connected to ASCII terminals or PCs are referred to as data telephones.
